BSNL GPRS plan
Not sending GPRS sending

I have activated GPRS plan on BSNL sim few days back. it just worked for 3 days after that it got deactivated by itself. I called several times to customer care but they showed no results. They said GPRS got deactivated or settings got deleted but after repeated requests they have not send me GPRS settings after giving 48 hours time period.

I am very much disappointed from BSNL service
